E(level): From a least-squares fit to Eγ, by evaluator.

Jπ(level): Spin, parity, and single-particle configuration assignments are based on decay patterns, multipolarity assignments, comparison with projected shell model calculations and on the analogy with rotational band structures in 77Kr and 79Sr.
